Five charts showing Australia’s energy transition is real — but uneven

Story pitch

This story aligns with Topic 3: Environment and ecology. Australia’s clean energy transition is often described through a single national headline: renewable energy is growing. While that is true, it hides a more complicated and more useful story. The transition is not happening evenly across fuel types, states, or the wider energy system.

Using publicly available Australian Government energy data, this five-chart visual story shows how renewable electricity has grown, which technologies are driving the change, and where fossil fuels still remain central. The story begins with the national electricity mix, showing that renewables now form a significant part of Australia’s generation, but fossil fuels still dominate overall supply. It then focuses on the changing role of solar, wind and hydro, before comparing differences across states and territories. A separate view of the broader energy mix shows why electricity progress does not automatically mean the whole energy system has transitioned.

The aim is to move beyond a simple success story or failure story. Australia’s energy transition is real, but it is uneven. Some parts of the system are changing quickly, while others remain dependent on older sources of generation. This makes the topic suitable for The Conversation because it explains a major environmental issue using accessible public data and helps readers understand why national averages can hide important local and technological differences.

Chart 1: Renewables are rising, but fossil fuels still dominate

The national electricity mix has changed significantly. Renewables made up 36.1% of electricity generation in calendar year 2024, compared with 8.7% in 1998–99. However, coal, gas and oil still accounted for nearly two-thirds of total generation in 2024.

Chart 2: Solar has become the fastest-moving part of the transition

The renewable story is no longer mostly hydro. Solar and wind have grown quickly, with solar generation rising especially sharply since the late 2000s. This change matters because the renewable transition is not one technology moving at one speed.

Chart 3: The national average hides very different state electricity systems

The same national transition looks different depending on where electricity is generated. Tasmania and South Australia have very high renewable shares, while New South Wales, Victoria and Queensland remain coal-heavy. Western Australia and the Northern Territory rely more heavily on gas.

Chart 4: The wider energy system is even less renewable

Electricity is only one part of Australia’s energy story. When the broader state energy mix is considered, oil, gas and coal still dominate many states and territories. This is why electricity transition progress should not be mistaken for a complete energy transition.

Chart 5: The uneven transition is clearest when states are compared directly

Tasmania and South Australia show what high-renewable electricity systems can look like. But the Northern Territory, Western Australia, New South Wales, Queensland and Victoria still depend heavily on fossil generation. The transition is therefore real, but not equally advanced everywhere.

Final takeaway

Australia’s energy transition is not a simple success-or-failure story. Renewable electricity has grown sharply and solar has become a major part of the system. But the transition is uneven: some states already generate most of their electricity from renewables, while others remain dependent on coal or gas. The wider energy system is even slower to shift, with oil, gas and coal still central to the primary energy mix.

The public story, then, should not stop at the national renewable share. The more important question is where progress is happening, what is driving it, and which parts of the system are being left behind.
